IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 168,15 l, datedSeptember 28, 1875; application led September 11, 1.875.

To all whom it may concern Be it known that I, EDWIN S. GEAUEL, ofDayton, in the county of Montgomery and State of Ohio, have invented anew and Improved Door-Oheck, of which the following isl a specification:

In the accompanying drawing, `Figure l represents a front view of myimproved doorcheck; and Figs. 2 and 3, respectively, Vertical transverseand horizontal sections of the same on theline .r x and y y, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention relates to a device for'. holding i the door open at anydesired point; and it consists of a sliding spring-acted plunger, withhinged head-piece and rubber extension, that is thrown by a projectingpin into contact with Y the iioor, and retained by the ends of theheadpiece locking into ratchet-teeth of the casing,

the rubber being drawn back into the casing on closing the door.

In the drawing, A represents a socket or casing, in which thespring-acted plunger B is which is provided, as well as the casing, with4a recess, d, to give play to the rubber. The

friction of the rubber on the door retains the same rmly at any desiredpoint, while end projections e of the hinged head-piece C lock intoratchet-teeth e at the interior of the casrigidly the position of therubber block. When the door is moved in opposite direction the4 rubberis turned back, and throws the projections or ends of the head-piece outAof the ratchet, so that the spring can move the plunger in upwarddirection, raising the rubber clear of the door, and allowing/theunobstructed closing of the door.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A door-check for holding the door open at any point,composed of a casing with front slot and interior ratchet-teeth, and ofa sliding and spring-acted plunger with hinged headpiece, having endprojections, and rubber eX- tension-block, for retaining the rubberfirmly in contact with the door, substantially in the manner and for thepurpose set forth.

2. The plunger-guiding casing and door,

provided with recesses at the lower part forgiving play to the curvingof the rubber when binding on the floor, substantially as specified.

EDWIN STUART GEAUEL.
